Overview

The GSM Adaptive Multi-Rate Wideband (AMR WB) speech codec is used in the UMTS and CDMA2000 and 3GPP mobile telephony systems. The codec supports wideband speech with a 16kHz sampling frequency resulting in much higher speech quality.

Benefits

Codecs are Fully Compliant: Bit exact thorough testing against standard and test vectors Codecs are Certified: E.g. codecs went through Dolby, Microsoft certification Robustness - no hanging: Codecs are thoroughly tested including floating inverted bits tests Error resilience: Dependent on standard, codecs fill gaps introduced by transmission errors Codecs developed in-house: Issues that may arise are quickly handled by Virage Logic?s in-house DSP experts Tested using a large suite of bitstreams: From standard holder, in-house generated, live generated, from customers, etc.

Features

Compliant to 3GPP and ITU standard Supports GSM-EFR, GSM AMR WB and G.722.2 Supports CNG (Comfort Noise Generation) Supports Packet Loss Concealment Supports Homing Mode Supports bitrates from 6.60 Kbit/s to 23.85 Kbit/s Supports sampling rate of 16 000 samples/s Low MHz and low power consumption for real-time operation Bit compliant with reference 3GPP TS 26.174 test vectors Supports ITUT, MIME, DEFAULT, and IF2 bit stream formats
